More than 300 Cosatu affiliates on Saturday marched through the Bloemfontein city centre and handed over a memorandum to the Department of Higher Education over the Reitz saga.

"Professor Jansen must just go. He will never help us transform that university," provincial secretary Sam Mashinini said.

Mashinini said they were prepared to intensify their actions to ensure that "Jansen goes".

He said they were angered that University of Free State rector Professor Jonathan Jansen dropped the charges against the Reitz four "before justice was done."

The four studying at the university, filmed an initiation of five black staff members in 2007. The employees, four women and a man, were seen on their hands and knees eating food which had apparently been urinated into by a white student.
